− Neutral position:
Neutral position will be selected via the Controller.
After the ignition is switched on, the electronics remains in the waiting state.
By the position NEUTRAL of the Controller, resp. by pressing the pushbutton NEUTRAL,
the EST-37 becomes ready for operation.
Now, a gear can be engaged.
− Starting:
The starting of the engine has to be always carried out in the NEUTRAL POSITION of the
Controller.
For safety reasons, it is to recommend to brake the vehicle always securely in position with
the parking brake prior to start the engine.
After the starting of the engine and the preselection of the driving direction and the gear,
the vehicle can be set in motion by acceleration.
At the start off, the converter takes over the function of a main clutch.
On a level road it is possible to start off also in higher gears.
− Upshifting under load.
Under load will be then upshifted, if the vehicle can continue to accelerate by it.
− Downshifting under load.
Under load will be then downshifted, if more traction force will be needed.
− Upshifting under coasting condition.
In the coasting mode, upshifting will be suppressed, if the vehicle speed on a downgrade
shall not be further increased by accelerator position idling speed.
− Downshifting under coasting condition.
Downshiftings in the coasting mode will be then carried out, if the vehicle shall be
retarded.
− Reversing
The reversing must be performed at standstill, resp. at very low driving speed.
Above the programmed reversing limit, the vehicle will be shifted to Neutral by
the Electronic unit EST-37, and the vehicle continues rolling in the previous dri-ving
direction.
The gear of the new driving direction will be only engaged when the program-med
reversing speed and the transmission input speed (turbine speed) has fallen
below.
The programming is customized and can therefore be different from standard.
Therefore, the exact procedure must be taken from the Operating Instructions manual
